B-SERIES CONDENSING UNITS

Master-Bilt offers its most complete refrigeration units in the built-up B-series. These condensing units, factory assembled on a galvanized steel channel leg base, are available from 3 to 40 H.P. Because components are pre-wired and factory mounted, field installation time is minimal. Field installation requires connections for electrical supply and refrigeration lines, evacuation and charging only. Built-up B- series units are available in hermetic, compliant scroll and semi-hermetic compressor models, with or without matching evaporator coils.

M-SERIES CONDENSING UNITS

Master-Bilt's M-series is very similar to the B-series in components and options. However, M series models are specially designed to function in high ambient temperatures. As with the B series, components are pre-wired and factory mounted.
M-series units are also available in hermetic, compliant scroll and semi-hermetic compressor models, with or without matching evaporator coils. They are factory assembled on a galvanized steel angle leg base, and range from 1/2 to 6 H.P.

PRS-2 SERIES PACKAGED REFRIGERATION SYSTEMS

The PRS-2 series combines a condensing unit and evaporator coil into one unit with everything ready to mount on the top or side of your Master-Bilt walk-in cooler or freezer. In fact, most indoor units come with a power cord so the unit can be plugged in.

PRS-2 ceiling units are available with stock PRS-2 walk-in sizes for five day shipment. Walk-ins with wall-mount PRS-2 units require longer lead time. Single or multiple units can also be specified for customized walk-ins with standard lead times. Other standard features of PRS-2 walk-in refrigeration systems include:
  • High efficiency fan motors
  • Condensate evaporator pan on indoor units to eliminate the need for a drain line
  • An evaporator section that mounts flush in a standard four-inch thick panel allowing maximum storage space.

MRS SERIES MODULAR MULTI-COMPRESSOR REFRIGERATION SYSTEMS

By remoting all refrigeration systems in their establishments, including those in reach-ins, walk-ins and ice machines, to a single MRS system, business owners can remove the heat produced by multiple refrigeration systems from their kitchen or store and reduce their air conditioning load.

This outside system, typically roof-mounted, also reduces noise level and extends the life of equipment.

The modular design of the unit also safeguards against catastrophic failure, should a section of the condenser be damaged. Each MRS system is composed of individual modules.

Each module includes a compressor with refrigeration components pre-piped to its own modular condenser. The MRS can house up to 16 modules. MRS units are pre-wired to an electrical panel for one-point connection. The compactly stacked condenser modules are designed for 110ļF temperatures but are also protected in cold weather conditions by integrated low ambient components, including head masters and crankcase heaters. The systemís galvanized steel housing (stainless steel finish available) provides further protection from the elements.

The MRS allows modules to be pre-piped to a central location area. The single roof penetration point reduces installation costs and chances of roof leakage. Because all the refrigeration components are housed in one unit, the system is also easier to service.

DRS SERIES DUAL-COMPRESSOR REFRIGERATION SYSTEMS

 

For applications calling for only a two-compressor system, the DRS series is the answer. A complement to the MRS series, DRS models share many of the same quality construction and features as well as fitting the same range of applications in hotels, c-stores, QSRs and cafeterias

DRS systems feature:
  • Multi-circuited condenser coil designed for 110įF ambient
  • Scroll compressors for freezer applications up to 5 HP
  • Hermetic compressors for cooler applications up to 3 HP
  • Common base and frame assembly
  • Standard galvanized finish with optional stainless steel finish

As with the MRS series, the Master Controller Reverse Cycle Defrost system is an option.

PS SERIES PARALLEL REFRIGERATION SYSTEMS

A parallel system, often referred to as a "distributed" system, is a multiple compressor refrigeration unit piped in parallel to yield smooth capacity control as compared to a single compressor unit. A parallel system can be located in a back room or on a roof in close proximity to refrigeration equipment for reduced piping.

PS series systems match refrigeration capacity to your actual load and can yield savings of 20% or more over a single compressor unit.

Master-Bilt PS series parallel units, matched to an appropriate condenser, may be modular allowing you to add or change compressors as needed. The standard rack housing and frame is made of durable galvanized steel with stainless steel as an option.

PS systems are designed to conserve energy in many ways:

  • A wide range of compressors is available, including digital scrolls, to better match capacity and budget needs while providing the most energy efficient and environmentally friendly system.

  • Optional subcooling increases refrigerant efficiency on low temp applications by approximately 17%

  • Optional heat reclaim increases energy efficiency by reclaiming waste heat from the condenser

  • Optional gas defrost increases energy efficiency by using waste heat for defrost

Electronic controller units are also available on PS systems. Choose from a variety of units depending on individual requirements such as monitoring of system features, diagnostics, interfacing with existing building controls and incorporating HACCP recording. Alarm features are also an option.

GPS SERIES GLYCOL PARALLEL REFRIGERATION SYSTEMS

Master-Biltís GPS series glycol parallel rack systems use the a highly efficient refrigeration system to chill a glycol loop which is, in turn, used to cool various refrigeration equipment in a foodservice kitchen or retail environment.

The GPS series system cools a brazed-plate heat exchanger which removes the heat from the glycol loop. The glycol is then circulated by a highly efficient variable speed pump to the kitchen fixtures. 

The most unique feature of the Master-Bilt glycol system is that it utilizes floating heat pressure technology to lower the energy consumption of the refrigeration system by as much as 25%. The system also uses full digital controls vs. mechanical controls in competitive equipment. These state-of-the-art digital controls provide greater precision, diagnostics, data logging and monitoring capability.

Along with energy savings, the biggest benefit of the glycol system is a reduced refrigerant charge which is completely contained within the wall of the parallel rack system. Only the chilled glycol is distributed to the kitchen. Less refrigerant and piping mean less chance of refrigerant leaks .

THE GLYCOL LOOP PROCESS
Glycol Parallel Rack system
Master-Bilt GPS series parallel rack systems circulate glycol through a loop, typically copper or ABS piping, to refrigeration equipment such as merchandisers, reach-ins and walk-ins. Return lines carry heated glycol from each piece of equipment back to the rack system for re-cooling.

E-SERIES EVAPORATOR COILS

E-Series evaporator coils are ready to mount in position and are available with air (off cycle) defrost, electric defrost or optional reverse cycle defrost when equipped with the Master Controller Reverse Cycle Defrost system. Each is also furnished standard with a properly sized expansion valve and room thermostat. Energy efficient EC motors are standard on single phase coils.

Electric defrost models feature defrost termination/fan delay controls and drain line heaters.
